The research at Hôpital Maisonneuve-Rosement, in Montreal, shows how life stressors such as obesity reprogram immune system cells and make them destructive to the eye as it ages. “We wanted…

Scientists make progress in decoding genetics of insomnia: Using a predictive genomics approach called variant-to-gene mapping, Texas A&M biologist Alex Keene and colleagues prove the gene Pig-Q is associated with sleep regulation in humans, flies and zebrafish.

A National Institutes of Health-funded effort involving researchers from Texas A&M University, the Perelman School of Medicine at the University of Pennsylvania and Children’s Hospital of Philadelphia (CHOP) has used human genomics to identify a new genetic pathway involved in regulating sleep from fruit flies to humans — a novel…

Today, only one rodent species remains within the island’s two countries of Haiti and the Dominican Republic, and its prospects for survival are uncertain. There are…

Scientists find evidence for magnetic reconnection between Ganymede and Jupiter: Juno spacecraft discovered magnetospheric fireworks as magnetic field lines merge and snap between the gas giant and its largest moon

In June 2021, NASA’s Juno spacecraft flew close to Ganymede, Jupiter’s largest moon, observing evidence of magnetic reconnection. A team led by Southwest Research Institute used Juno data to examine the electron and ion particles and magnetic fields as the magnetic field lines of Jupiter and Ganymede merged, snapped and…
